Description

Professor David M. Kehoe from Department of Biology, Indiana University will give a special seminar, Light Color Acclimation in Marine Synechococcus: Molecular Mechanisms, Regulation, Evolution and Ecological Role, on Thursday, 25th July, 12 - 1pm in 4WW 322 seminar room. All welcome!

ABSTRACT

Marine Synechococcus, the second most abundant phototroph on Earth, thrives in various light niches in part due to its varied photosynthetic light harvesting pigments. Approximately 40 percent of Synechococcus cells worldwide use a process known as chromatic acclimation to optimize the ratio of two chromophores, green-light absorbing phycoerythrobilin (PEB) and blue-light absorbing phycourobilin (PUB), within their light harvesting complexes. A mechanistic understanding of how Synechococcus cells tune their PEB to PUB ratio during chromatic acclimation has not yet been obtained. We have assembled a team of laboratories who are using biochemistry and molecular genetics, in tandem with comparative and functional genomics and phylogenetics, to unravel the chromatic acclimation mechanism and its regulation by blue and green light. These studies are also allowing insights into the global ecology of this trait and its evolution.

BIOGRAPHY

Dr David M. Kehoe is a Professor of Biology at Indiana University. He completed his PhD at University of California, Los Angeles and was the NSF Postdoctoral Fellow at Carnegie Institution, Stanford University. He has won numerous awards including American Association for the Advancement of Science Fellow in 2018. His research group is broadly interested in uncovering the molecular mechanisms that control how organisms sense and respond to changes in their environment, primarily focusing on marine and freshwater cyanobacteria.
